Timer 2 caculation

Small problem, I didn't have a weather station yet. He was using his, I do have the DA from his notes.

Stop rpm- 4000, Ratio from notes is 8.7:1. I only have times using the stop. They were as follows:

10.993- 3400 DA- 1.860 timer 2
10.923- 2400 DA- 1.860 timer 2
10.877- 2400 DA- 1.460 timer 2
10.903- 2400 DA- 1.660 timer 2

His math was- 10.90-10.8777=.023. .023x8.7=2.00. Old timer 2 # of 1.460+.200=1.660 is new timer 2.

Thanks guys I purchased a weather station and Crew chief Pro for next season.

I see there was a thousand ft differance in air, did that also end up in your ratio ?

As far as I know it was .067 per 1000 feet.
